-Subject: [PATCH] listdir(): reuse a single buffer to store every file name to
- display
-
-Allocating a new buffer for each entry is useless.
-
-And as these buffers are allocated on the stack, on systems with a
-small stack size, with many entries, the limit can easily be reached,
-causing a stack exhaustion and aborting the user session.
-
-Reported by Antonio Morales from the GitHub Security Lab team, thanks!
